90373 - Ground Vehicle Dynamics M

Learning outcomes

This course provides basic concepts about the dynamics of ground vehicles. The students who attend this class acquire the necessary competencies to model, understand and analyse the dynamics of ground vehicles by means of the linearization of nonlinear models, determination of the associated modes and the analysis of their stability.

Teaching methods

Presentations, Videos, Blackboard, Electronic Board, Microsoft Teams, Computer Simulations, MATLAB, Simulink.

Assessment methods

The exam consists of a group (max 3 students) project in which the students model the dynamics of an automotive system. The group must provide a technical report and the simulator on which the proposed solution is tested. The project is developed in tight collaboration with the teacher in agreement with a recursive "submit and review" process.

The exam is a satisfactory/unsatisfactory grading.

To pass the exam the students must know the good practices to model the dynamics of automotive systems.

The exam modality is unquestionable and is also valid for ERASMUS students.

Attendance is not necessary to take the exam.

 

Policy on the Use of Artificial Intelligence in Assessment Activities

Artificial Intelligence (AI) can be a useful tool to support individual study through in-depth exploration, summarization, and self-assessment activities. With regard to the assessment of learning:

• substantial use of AI is permitted for project development (for example, in problem solving and content generation).

• the project presentation is based on the critical analysis of theresults produced. The use of AI is prohibited during the presentation. Any use constitutes a violation of academic integrity.

Teaching tools
